Latem Patent N 106,775, dated Augmtso, 1870;

IMPROVED MACHINE FO'R 'UPSETTING- TIRES.

The Schedule referred tg in these Letters Patent and making part ofthe same.

, To all whom it may concern:

Be it known that I, WILLIAM BOWDEN, of the town of Hamburg, county of Erie and State ot New York, have invented a certain new and useful Improvement-.in Devices for Upsettiug Tires, of which the following is a specification.

` Natura of Invention. This invention relates to au improvement in ma- .chines for upsetting tires.

General Description. In the drawing- Figure l is a perspective view with the tire in place, and v Figure 2, a similar view with the tire removed.

A is a cast-iron block, formed 'with concaves p p on thereverse faces, and having posts or studs a. a' a c at the corners, which serve t-he double purpose of legs, on which the block stands, and as fastenings for the wedges and keys, as hereinafter described.

The inner faces s of the studs a a are made straight, and receive plain keys e e, against which the edge of the tire rests when the tire is a very narrow one.

The faces s' s' of the opposite studs a' a' are made wedge-shaped longitudinally, and slightly dovetailed horizontally, and a serrated wedge, d, is driven lin between it and the edge of the tire, so that every blow struck on the tire forces this wedge in tighter, and iniiexibly holds the tire until hammered down to compress the metal. This construction is'the same on both sides, and therefore it can be reversed, and both sides used, one for light and the other for heavy tires,v

the spaces b' on the other side being merely made wider. Y

shape of the block conforms to the circle of the tire.

rated wedge d on the other, and driven in. Then the tire is hannuered out Hat, to compress the met-al, the whole operation taking but a fewminutes;

The novelty in' myinventiou consists simply in the construction ofthe block, withltthereverse eoncaves p11 and the posts a a', which leave the wedge-shaped and dovetailed spaces between for theinsertiou of the keys and wedges.

I am aware that keys and wedges have before been used, also blocks of "arious forms; but no block, so far as I am aware, of the form 1 have above described.

It is exceedingly cheap and simple, and eau be made by any workman.

Ihe improved apparatus herein described, consisting ofthe block A, havitg the reverse concavesp p' and the stv-nds a at', formingwedge-shaped and dovetailed spaces s s', for the' insertion of the keysc, and serrated wedges d, the whole arranged as described and operating in the manner and for the purpose specitied.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses. WILLIAM BOWDEN. Witnesses:
